Abstract - In our project we come with inventive idea
about intelligent braking system implementing with pneumatic bumper. The system comes up with solar plate that works on Non-conventional energy source so that this system also works on up coming solar vehicle which is future of automobile industry. The system is presented using prototype model for analyzing its various parameters and limitation for daily utilization. Intelligent braking system with application extended pneumatic bumper is the safest way to protect passenger from rough motion and harm. The main motive of this project is to protect passengers from the object that suddenly comes in way of vehicle and prevent the collision of obstacle with vehicle. Here ultrasonic sensor plays the crucial role for detecting the obstacle and activation of pneumatic bumper. Design and application of this braking system depends on produce capabilities of sensors and pneumatic bumper.
Braking Distance: It is distance between the point at which brakes are applied and the point at the vehicle completely stops
The formula of braking distance is given by, Braking distance = V2/2µg Where , V= Velocity of the vehicle (m/s) µ = Friction coefficient of road = 0.8 g = Acceleration due to gravity = 9.81(m/s2)
Key Words: Ultrasonic sensor, pneumatic bumper, solar, road safety.

1.INTRODUCTION The number of vehicle on road are increasing rapidly therefore chances of road accident also increases. The road accident are major problem in India especially in urban areas. According to report of Ministry of Road transport and Highways, Total number of accident on Road are 4,49,002 and 1,51,113 person are been killed due to road accident by the year of 2019. The braking system of commercial vehicle are having higher priorities. The Small error in braking System can lead to major accident. In our project we fabricate the prototype model of intelligent braking System That works on solar energy so that it can able to work in upcoming solar vehicle.
Factor considered in designing the System are:
Distance of obstacle in front Speed of vehicle
Speed of vehicle

Impact Factor value: 7.529
Speed of Vehicle: Braking distance of vehicle is extensively depends on speed of vehicle
An Proximity Sensor is fixed over in front of vehicle. 10 Watt Powered solar plate provide power to the whole circuit. As Solar plate connected to battery using MPPT (Maximum power point Tracker) charges battery. The speed of vehicle and distance of obstacle in front of vehicle calculated by proximity sensor gives real time input to the relay circuit. As soon as sensors detect the stationary or moving vehicle or obstacle in front of , if driver does not take necessary action or does not applied the brake of vehicle by the time relay circuit activate and it stops the DC Gear motor. Control flow valve is also gets activated and it supplies a required quantity of air in pneumatic cylinder. The pressure is built inside a cylinder which tends to push a rod outward and it avoid collision with the other vehicle.
2.1 Factors Considered
